Copper is well known for its grasping capacity. It grasps the divine spirit (sattvikta) upto 30%, when compared to other metals. Copper can destroy bad spirits like Raj & Tam (i.e. darkness & bad behavior). The spiritual vibrations are attracted towards copper items easily. Just as copper has the ability to absorb the sattvik frequencies of deities, it has also capacity of transmitting them. Thus it becomes rich in divinity in a short period.
